Lighting Features
Entry Lighting
The dome lamp, cargo lamp, and
foot lamp inside the vehicle come
on when any door is opened, if the
dome lamp is in the door position. In
addition, these lamps come on
when the Remote Keyless Entry
(RKE) unlock button is pressed.
They stay on for 20 seconds or until
a door is opened. After the door is
opened and then closed, the light
remains on for 20 seconds, or until
the ignition is turned to ON/RUN.
Battery Load
Management
The vehicle has Electric Power
Management (EPM) that estimates
the battery's temperature and state
of charge. It then adjusts the voltage
for best performance and extended
life of the battery. When the battery's state of charge
is low, the voltage is raised slightly
to quickly bring the charge back up.
When the state of charge is high,
the voltage is lowered slightly to
prevent overcharging. If the vehicle
has a voltmeter gauge or a voltage
display on the Driver Information
Center (DIC), you may see the
voltage move up or down. This is
normal. If there is a problem, an
alert will be displayed.
The battery can be discharged at
idle if the electrical loads are very
high. This is true for all vehicles.
This is because the generator
(alternator) may not be spinning fast
enough at idle to produce all of the
power needed for very high
electrical loads.
A high electrical load occurs when
several of the following are on, such
as: headlamps, high beams, fog
lamps, rear window defogger,
climate control fan at high speed,
heated seats, engine cooling fans,
trailer loads, and loads plugged into
accessory power outlets.
